My first job out of college was a Mold Design Engineer for the automotive tooling industry. I created 3D models in SolidWorks for various industrial parts, (like benches, tools, and molds). The three-part headrest mold was created using complex surface modeling in SolidWorks, and its accompanying carrier was produced with much more simple 3D modeling tools in SolidWorks. The swing cylinder was also produced in SolidWorks. All of these were produced for manufacture at CP Industries. The swing cylinder was produced by me for CNC tooling, in discussions with the machinists.
